WATERPROOF PAPER UMBRELLA.

Application filed March 25, 1922. Serial No. 546,864.

To all whom it may concern:

Be it known that we, GEORGE B. CANNON, Jr., and FRANK W. HOWARD,citizens of the United States, residing at Brookl n, in the county ofKings, and at Mount ernon, 1n the county of Westchester, respectively,and State of New York, have invented new and useful Improvements inWaterproof Paper Umbrellas, of which the following is a specification.

This invention relates to umbrellas, and while features of the inventionmay be ap plicable to umbrellas having cloth covers, the invention ismost useful when applied to the construction of inexpensive paperumbrellas.

The general object of the inventionus to produce an umbrella of thistype having a cover which can be readily attached to the frame, and inwhich the frame and cover are constructed in such a way as to reduce thestrains and prevent the cover from being torn from the frame by thewind.

Further objects of the invention will appear hereinafter.

The invention consists in the novel features, and in the generalcombination of parts to be particularly described hereinafter, all ofwhich contribute to produce a simple and eflicient water-proof paperumbrella.

A preferred embodiment of the invention will be particularly describedin the following specification, while the broad scope of the inventionwill be pointed out in the appended claims.

In the drawing,

Figure 11: is a erspective showing the portion of this strl at the foldwhere the direction of the strlp must change near the crown.

In practicing our invention we provide a frame very similar to anordinary umbrella frame, that is to say, it comprises a stick 1, andribs 2 which radiate from the umbrella The ribs 2, however, are mothinged to the crown, but have flattened ends as illustrated in PatentNo. 1,229,271, which are clamped by the crown against the side of thestick and are flexed when the ribs are extended by means of thestretchers 4 which are attached to a runner 5 on the stick. The umbrellacover 6 is composed of a plurality of sections 7, 7, etc., correspondingto the spaces between the ribs.

In applying the invention, sleeves 8 are provided which are attached tothe inner side of the cover and extend inwardly from the outer edge ofthe cover. These sleeves preferably extend all the way up to a point atthe crown, but near the e es 9 to which the stretchers 4 are attachethese sleeves are provided with openings 11, respectively which ermitthe outer end of the ribs to be inserted and slid outwardly, inattaching the umbrella cover.

Figure 5 illustrated the simplest construction for the sleeve, and forattaching the same to the adjacent umbrella sections. The two adjacentumbrella sections are simply held with their adjacent edges together andthe side edges of a strip of paper are then sewed completely through thesame by means of stitches 10. In this way, one row of stitches operatesto form the sleeve and secure the two adjacent cover sections together.

.the ribs.

means or method maybe employed for the u'mbrella'construction at thecrown. The invention disclosed herein relates especially to the meansfor connecting the ribs to the umbrella cover and for reinforcing thecover vided with an openlng or inclined slot 11 (see Figure 2) and atthese slots the material of the sleeve is preferably reinforced by ashort reinforcing strip 12 (see Figure 2). The ends of the umbrella ribsare provided with means toprevent them from injuring the cover in anyway. This is preferably accomplished by providin enlargements orenlarged heads 13 on t e ends of This head may be formed simply bybending the end of the rib into a closed eye. It is important that theseeyes should be completely closed because otherwise they tend to becomecaught in other parts and interfere .with the manufacturing of theumbrella. In order to strengthen the outer edge of the umbrella cover astring or cord 14 is laid along this edge (see Figure 3) and the edge isthen turned over so as to form a hem 15 attached by stitches 16 to thebody of the cover. The ends of this cord are attached together so thatit operates to resist any force tending to enlarge the diameter of theumbrella at this point. Instead of having a diagonal slit 11 as shown inFigure 2, an opening 17 may be provided (see Figure 6). This opening isof oval shape and is such as would be formed by punching out a smallarea of the material. 11 this case also the material of the sleeve ispreferably reinforced by a reinforcing piece 18.. In assembling theumbrella the enlarged head or eye in inserted through the slit andshoved outwardly down the sleeve, the head or eye 13 being smooth andround facilitates the thrusting of the rib through the sleeve-withoutinjuring the paper, and after the rib is in place this head also tendsto prevent the end of the rib from puncturing the paper near the edge ofthe cover.

The upper portion of the sleeve 8 lies between the rib and the cover andtends to distribute the pressure of the rib against the cover, therebyincreasing the strength and durabflity of the umbrella at this point.The eye on the end of the rib is preferably formed in substantially thesame plane as As a matter the axis of the umbrella stick (see Figures 8and 9), that is to say, the plane inwhich the eye is formed liessubstantially at right angles to the cover. After the rib has been sliddown into place the projecting end portion 19 of the sleeve is thenfolded around so as to lie over'the eye or head 20. This folded over endcan then be secured to the eye by any suitable means, for example, bymeans of a small wire staple 21 which may be shoved through it andagainst the eye. The curved sides ofthe eye operate to turn the pointsof the staples as they come against them. The adjacent portion of thesleeve is preferably provided with a reinforcing piece 22. Thesereinforcing pieces may be made of stiff paper or stout woven tape.

In view of the fact that the up er portions of the sleeves should alwayshold themselves between the rib and the cover, the openings 11 and 15will be sufiiciently short to insure that this would take place.

Where. the cover sections 7 are attached together near the crown 3 ofthe umbrella they are cut so as to produce a projection or nave 23 inthe cover adjacent to the crown. In order to produce this effect theadjacent edges of the umbrella sections are out in a curve (see Figure10). It is not feasible to bend the paper strip 8 readily along a curvedline and in order to enable the strip to adapt itself to this generalshape we provide it with one or more folds 8 having the generalcharacter illustrated in Figure 11. That is to say, the bifurcated orcreased strip is buckled into itself so as to form a transverse doublefold. By having this fold wider on one side than the other the directionof the strip will be changed to make it conform to the general directionof the attached edges of the sections. See Fig. 10. These folds,however, do not interfere. in any way with the sewing of the stitches 10on a sewing machine, and have the effect of a reinforcement at thispoint.
